IIWPROVEMENT IN WATER-ELEVATORS.

The Schedule referred to in these Letters Patent and making part ,of the same.

To all whom 'it 'may concern:

Beit known that I, WILLIAM M. PALMER, of Middlebush, i'n the county of Somerset, and State of New Jersey, have invented a new and useful Improvement in VVatcr-Elevators; and I do hereby declare thatthe following is a full, clear, and exact'description of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure l is an elevation of my improved elevator, showing one of the buckets attached;

Figure 2 is atop view, showing the arrangement of the 'iction-pulleys, the clutch-ci'mplings, and a portion of the mechanism for reversing or shifting the clutchcoupling Figure 3 is a sectional elevation 1; and l Figure 4 is a transverse vertical section on line x x of fig. 2.

Corresponding letters in the several ligures.

'I his invention relates to water-elevators for wells; and

It consists in the combination and arrangement of the' parts for raising and lowering the buckets, and for retaining the buckets in any desired position within the well; and further, for furnishing the means of lowerin g the buckets further from the drums by which they are raised and lowered in case the water in the well falls to a lower level than that which it had previously occupied.

And it further consists in providing the buckets for drawing the water with an additional bail, and a weight, or a weighted bail, so arranged, with reference to said bucket, that it will insure the propersinking of the bucket in the water, and cause the same to assume the proper position before leaving the water, to insure its being filled therewith.

A, in the drawings, represents the cu'rb of a well, which' may be of any suitable construction, which is adapted to receive the standards B, which support the windlasses, with the parts connected therewith.

B B represent standards, which are secured to the curb of thc well, one upon each end thereof, they forming the bearings in which the joiunals of the windlasses run.

C represents the spout through whichthe water flows when delivered thereto from the bucket or buckets.

l) represents the handle, or crank, which is placed outside the curb, but upon the end ofthe shaft which passes through the. drums around which the rope. or chain passes in raising the buckets.

E E represent dru1us,\vhich are to be made ofwood, or ofwood and metal united, those shown in the figure being of the last-named class, and having wooden centres, with a metallic head, or iin-nge, upon their outerends, while their inner ends are supplied with friction-pulleys, the oilice of which will bc hereafter described.

F F represent friction-pulleys, which have a V- on line g/ y of iig.

refer to corresponding parts shaped groove formed in their peripheries, and which are bored out or otherwise ttted' to the ends of drums E E', they serving the double purpose of a ange, or head, for the inner head of such ldrums and frictionrollers, to regulate the movements of the buckets.

G represents a rope or band, which passes around the friction-pulleys F F, and around sheaves, or pulleys I and H, which serve to hold the belt or rope in position. Y t

H represents a sheave, or pulley, whichis secured to an arm made'fast upon a bar, or beam, which extends from one of the upper ends of the standards B to the other. This pulley is to be of such a diameter that a in its periphery, will be held at a proper distance apart to cause it to run in the grooved pulleys F F,and with binding or pressing either side of the same.

I represents a sheave, or pulley, which is attached to the bar, or beam above alluded to, by means of a spiral or other form of spring, which spring forms the bearings of a cross-arm, or shaft, which is formed upon the square portion of the arm 'upon which the pulley revolves. lhis pulley is so arranged, with reference to way between such pulleys, and. it is to he of a diameter so much less than the pulley H, that the rope or belt G, which passes around both, and around the i`riction-pulleys, shall not come in contact with that portion which is travelling toward the pulley H while any other portion thereof is travelling toward pulley I. The office of the lastdescribed pulley is twofold: first, as a consequence of its arrangement and its connection with the spring K, it serves to keep the rope or belt bearing upon the friction-pulleys to such an extent as to held the buckets in any desired position inthe range of their travel; and secondly, by simply pressing downward or inward upon it, the rope or belt will be so far released from its contact with the pulleys as to permit the strap or chain which winds around the drums, and is attached to the buckets, to be unwound, so that the bucket may be lowered in the well to accommodate the varying height of watertherein, the hook a, fig. l,being designed to retain the drum E in position while E is being opera-ted upon. lhe same effect may be produced by passing a pin through the curb and into the flange of the drum.

K represents the spring above alluded to, the coustruction and arrangement of which are cleaily shown in fig. l.

L represents a vertical lever, the lower end of which is pivoted to any convenient point upon the well-curb, its upper end extending above the same, and terminating in a Vsuitable handle for operating the same, it being located upon that end ofthe curb which is nearest the crank ot' the windlass. t

M represents a connecting-rod, which extends horizontally from the lever above referred te, to one arm of lever N, which is pivoted to the. upper edge of the rope, chain, or strap, running in the V-shaped-groove the friction-pulleys F F', that its axis of motion is midcurb, or'to a standard secured thereto at a point midway between the pulleys F F', between which it passes, and is made to entera groove formed in the double clutch 0 O', by means of its bifurcated ends. This lever has an arm extending at a right angle to the body thereof, and resting uponthe upper edge of the curb, where it is guided in its movements by means of a clasp, or staple, placed over it and secured to the curb. 'lhe outer end of this lever is provided with a series of holes, to which the connecting-rod M may be attached.

0 O' represent a double clutch-coupling, which, as above described, receives the end of lever N, by which it is moved upon the shaft D' of the windlass. This clutch is located centrally between the friction-pulleys F F', and, as it is moved tothe right or left, engages with corresponding clutches formed upon the inner faces of such pulleys, the object of which arrangement is to enable the operator to raise either of the buckets and lower the other one at the same time, and without reversing the motion of the drums, by simply changing the position of the clutch, by means of braces Land N, thus causing the clutch to engage with either one or the other of the pulleys, at the pleasure of the operator.

P P represent the clutches, formed as above described.

l represents the bucket, which in fig. 1 of the drawings is shown as attached to the chain which winds around the drum E. This bucket may be made in any desirable form, and of any material which may be preferred; but when made of metal, its bottom should he of wood, for the purpose of facilitating the operation of dipping when it is lowered into the water. It however differs from other buckets in use, in that it 'has a weighted bail attached to it, at a point below its centre, the object of which is to cause the bucket to always assume a vertical position before it leaves the water, and thus insure its always being filled with the same. rlhis weighted bail is attached to the bucket by means of loops, or rings, formed in its outer ends, while rings engage with a staple secured to the bucket, at parts above the centre of gravity thereof, and below the same at its respective ends, so that as its lower end enters the water, the buoyancy of its bottom end shall cause it to tilt, and permit the water to low in at the topend and till it, when, in consequence of the bail proper being secured at a point above the centre of gravity, the tendency is to cause the bucket to assume a vertical position when the action of the windlass is brought to bear upon the same, which tendency is largely aided, and the accomplishment of the result made certain by means of the weighted bail.

2, in the drawings, represents the weighted bail above described, at which ligure its arrangement, with reference to the bucket, is clearly shown. This bucketis provided with the usual projecting pins upon its upper end, for engaging with a rod, or bar of iron, which is attached to the curb atasuitable point for tilting said bucket, and emptying it of its contents as the buckets are raised. l

Having thus described my invention,

What I-claim, and desire to secure by Letters Patent, is

l. The combination and arrangement of the sheaves, or pulleys H I, spring K, and rope or belt G, substantially as and for the purpose described.

2. The parts enumerated in the above clause, in combination with the friction-pulleys F and '.F', substantially as shown and described.

3. The arrangement of the pulleys F F', drums E E', rope G, pulleys H and I, and spring K, for the purpose of regulating the position of the buckets with reference to the surface of the water in the well, substantially as shown'anddescribed.

4. The arrangement of thele'vers LN, double clutchcoupling O O', and clutches P P', substantially as and for the purpose described.

5. The bucket 1, having a weighted bail attached thereto, substantially as shown and described.

In testimony whereof, I have signed my name to this specification, in the presence of .two subscribing witnesses.
